Abstract: An embodiment of the present disclosure discloses a wireless charging device comprising a wireless receiving module, a controller, a first charging module, and a second charging module. The wireless receiving module is configured to receive a wireless charging signal in response to the wireless charging device being in a wireless sensing area, transmit a state indication signal to the controller, receive a charging indication signal from the controller, and determine whether to transmit the wireless charging signal to the first charging module according to the charging indication signal.

Abstract: A toolbox system includes a storage box and an external hanger assembly. The storage box has an accommodation cavity for storing an item. The storage box includes a limiting portion formed on a housing of the storage box. The external hanger assembly is used for detachably connecting the item. The external hanger assembly includes an external hanger capable of detachably connecting the item. The limiting portion includes a limiting surface and/or a limiting hole mating with a mounting portion of the external hanger assembly.

Abstract: An image analysis system automatically determines a positioning and orientation of objects in an image. The image analysis system may be configured to evaluate images and determine whether the orientation and position of objects depicted in the images meet acceptable parameters. The image analysis system may process image data associated with an image to identify edges present in the image, and determine object lines based on the edges. Once the lines are identified, the image analysis system determines vanishing points for sets of the object lines. The image analysis system may then estimate camera parameters and determine the orientation of the objects as depicted in the image based on the vanishing points.

Abstract: The present invention relates to a pre-stressed insulated tubing, including an inner tube (3) and an outer tube (2) nested outside of the inner tube (3), and a closed ring cavity is formed between the inner tube (3) and the outer tube (2), wherein an insulated casing (4) is arranged in the closed ring cavity. The pre-stressed insulated tubing of the present invention features high vacuum degree, high thermal insulation level and long working life, and the insulated casing is reusable for cost saving.
